The learning connection
A multi-week project that produces a tangible result (from food scraps to usable compost) demonstrates a systems concept — circular economy — that cannot be adequately grasped in a single lesson. The time investment creates personal stakes that accelerate understanding of decomposition, nutrient cycles, and sustainability.
